Non-Isolated Power Supply

As Figure 21 shows, an external dc supply must be connected on a two-pin terminal block J8 to power the non-isolated section of the TIDA-00454 board. The TIDA-00454 design uses the TPS7A65-Q1 LDO. The DVCC for the MSP430F67791A device is 3.3 V. The power supply is protected for reverse polarity and overvoltage.
